	Encyclopedia: Faraday cup (Site not responding. Last check: 2007-11-06)
		Essentially the faraday cup is part of a circuit where ions in the gas phase act as charge carriers during part of the circuit and the faraday cup is the interface to the solid phase where electrons act as the charge carriers (as in most circuits).
		Faraday cups are not known for sensitivity but are highly regarded for accuracy because of the one-to-one relation between the two parts of the circuit and our ability to measure current accurately.
		The Faraday cup 38 is constructed of copper and is 25 mm in diameter and 35 mm high, the insulators 39 and 44 are constructed of a high melting point, electrically insulating material, such as a ceramic with the plug 37 and cup 42 being constructed of the same material as the Faraday cup (copper).

	Faraday Cup (Site not responding. Last check: 2007-11-06)
		No, the Faraday Cup is not a trans-Atlantic boat race, it's a device for precisely measuring the current carried by a beam of particles.
		The Faraday cup shown in the image above is the one used at Bates, which was recently completely overhauled and refurbished with the technical assistance of Jeff Shaw.
		Because the Faraday cup absorbs all of the beam's energy, it, of course, cannot be used to measure beam current during an experimental run.

	Faraday cup - Patent 4608493 (Site not responding. Last check: 2007-11-06)
		The present invention relates to so-called Faraday cups used for measuring various parameters associated with an electron beam, and more particularly is directed to a Faraday cup adopted for measuring the width, current density and energy density of an electron beam of generally strip-shaped cross-section.
		Accordingly, the time required for the cup current to change from a minimum value to a maximum value is the same regardless of the orientation angle, and the measured beam width is not subject to variation and consequential error due to variation in the orientation angle.
		Operation of Faraday cup structure 10 is as follows: Electron beam 25, which travels in a direction transverse to the length of its strip-shaped cross-section, is relatively displaced across cup structure 10 so that impact area 25a scans opening 17a.

	The Faraday
		For each positive ion that enters the faraday, an electron is drawn from ground through the current meter to neutralize the positive charge of the ion.
		The control system senses beam current which passes through one or more apertures in the disk and is collected by a Faraday cup.
		This current is integrated to obtain a measure of charge which is compared with a calculated value based upon the desired ion dosage and other parameters.
